¡Solidaridad! Periódico mural del Socorro Rojo de España Campaña de invierno.
Els dibuixos i la fotografia van acompanyats de diversos textos del periòdic relatius, tots ells, a la campanya d'hivern, amb una llista de donatius oberta a aquest efecte. Hi ha també una poesia de José Herrera Petere Una mà tendeix una manta sobre una dona amb dos xiquets. Altres dues figures oferixen també robes d'abric. Sobre elles un soldat en una trinxera i a l'esquerra fotografia de Manuel Azaña

A la dreta del cartell apareix reproduït un article editorial de Luis Zapirain titulat: "La campaña de invierno, movilización unánime del pueblo español" En la part esquerra del cartell fotografia de tres soldats molt somrients; a la seva dreta diverses fotografies de robes, queviures, xiquetes en les colònies infantils treballant en la confecció de jerseis per als combatents i un grup de soldats en formació
Asturias Octubre 1934-1937 Hoy como ayer el Socorro Rojo de España cuidará de vuestras familias
1937
Un dinamiter amb un fusell penjat en el muscle esquerre, està a punt de llançar un cartutx de dinamita amb la mà dreta; en la gorra duu les sigles U.H.P. [Unión de Hermanos Proletarios]. Al peu del dibuix s'estén un filat i a l'esquerra una mare amb dos nens
Regularization of spherical and axisymmetric evolution codes in numerical relativity
2007
Several interesting astrophysical phenomena are symmetric with respect to the rotation axis, like the head-on collision of compact bodies, the collapse and/or accretion of fields with a large variety of geometries, or some forms of gravitational waves. Most current numerical relativity codes, however, can not take advantage of these symmetries due to the fact that singularities in the adapted coordinates, either at the origin or at the axis of symmetry, rapidly cause the simulation to crash. Because of this regularity problem it has become common practice to use full-blown Cartesian three-dimensional codes to simulate axi-symmetric systems. In this work we follow a recent idea idea of Rinne…
Coastal zone water quality: Calibration of a water-turbidity equation for MODIS data
2013
AbstractA nephelometric turbidity algorithm has been specifically calibrated for coastal waters in Sicily. To this purpose, intensive field campaigns were performed in July, August and September 2008. Measurements were collected in situ in three different gulfs. Statistical analysis suggests that field data should be spatially grouped but temporally separated; hence, new calibration parameters have been proposed.Turbidity retrieved by applying the algorithm using literature coefficients and the ones calibrated in situ are shown and compared. The comparison demonstrated that a specific calibration was necessary for quantitatively monitoring turbidity in Sicilian gulfs.
A new hybrid procedure for the definition of seismic vulnerability in Mediterranean cross-border urban areas
2016
Assessment of seismic vulnerability of urban areas provides fundamental information for activities of planning and management of emergencies. The main difficulty encountered when extending vulnerability evaluations to urban contexts is the definition of a framework of assessment appropriate for the specific characteristics of the site and providing reliable results with a reasonable duration of surveys and post-processing of data. The paper proposes a new procedure merging different typologies of information recognized on the territories investigated and for this reason called “hybrid.” Knowledge of historical events influencing urban evolution and analysis of recurrent building technologie…
Binary logistic regression versus stochastic gradient boosted decision trees in assessing landslide susceptibility for multiple-occurring landslide e…
2015
This study aims to compare binary logistic regression (BLR) and stochastic gradient treeboost (SGT) methods in assessing landslide susceptibility within the Mediterranean region for multiple-occurrence regional landslide events. A test area was selected in the north-eastern sector of Sicily (southern Italy) where thousands of debris flows and debris avalanches triggered on the first October 2009 due to an extreme storm. Exploiting the same set of predictors and the 2009 event landslide archive, BLR- and SGT-based susceptibility models have been obtained for the two catchments separately, adopting a random partition (RP) technique for validation. In addition, the models trained in one catchm…
Integration of fuzzy logic and image analysis for the detection of gullies in the Calhoun Critical Zone Observatory using airborne LiDAR data
2017
Abstract The entire Piedmont of the Southeastern United States, where the Calhoun Critical Zone Observatory (CCZO) is located, experienced one of the most severe erosive events of the last two centuries. Forested areas were cleared to cultivate cotton, tobacco, and other crops during the nineteenth and early twentieth century and these land use changes, together with intense rainfalls, initiated deep gullying. An accurate mapping of these landforms is important since, despite some gully stabilization and reforestation efforts, gullies are still major contributors of sediment to streams. Mapping gullies in the CCZO area is hindered by the presence of dense canopy, which precludes the identif…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2003
Se discuten algunas de las conclusiones de varios trabajos históricos recientes sobre Amedeo Avogadro y la teoría atómica del siglo XIX. A través de pequeños extractos de publicaciones famosas de Avogadro, se analizan las características principales de sus aportaciones a la teoría atómica del siglo XIX. También se analizan los principales métodos de cálculo de pesos atómicos de esos años y se discute el papel de las ideas de Avogadro en este tema. Estas conclusiones se contrastan con la imagen que actualmente los libros de texto dan acerca de este autor. Finalmente, esta última comparación conduce a una discusión sobre el papel de la historia de la ciencia en los libros de texto. This paper…
Gli atti di disposizione
2013
Il saggio prende in esame la disciplina degli atti di disposizione del proprio corpo nella prospettiva del limite che essa pone all'autonomia dei privati, scrutinandone il significato e la portata attuali alla luce dei mutamenti intervenuti nel sistema, dopo il varo dell'art. 5 del codice civile, anche per effetto della normativa comunitaria e, in particolare, della Carta dei diritti fondamentali dell'Unione europea. Specola privilegiata di indagine sono le previsioni in materia di consenso nelle fattispecie dispositive di organi, di cellule e tessuti umani a destinati ad applicazioni (trapianto, innesto, infusione) su soggetti terzi. Nel persistente richiamo della normativa di settore a li…
